To all whom it may concern.-

Be it known that I, LEVERETT BRAINARD, of Hartford, Connecticut, haveinvented certain new and useful Improvements in Books, of which thefollowing is a specification.

My invention relates to the class of books which are so bound that theleaves will lie fiat at whatever page the book is opened, the objectbeing to so construct the fan-shaped stub-strip that it will be veryfirm and stiff, and yet can be easily sewedto the signatures andformastrong flexible joint between them.

Referring to the accompanying drawings, Figure 1 is an edge view of abook embodying my improvement. Fig. 2 is a detail view of aportion ofthe stub-strip. Fig. 3 is a detail View, on an enlarged scale, of aportion of the end of a book embodying my improvement.

In the drawings, the letter A denotes the stub-strip as a whole, whichis made up of two pieces of thin textile fabric a b, as cambric ormuslin, pasted together, between which, before pasting, a number ofstiffening-strips c, preferably'cut from paper, have been placed a shortdistance apart. These strips extend across the stub-strip the length ofthe book and are a little less in width than it is desired thestub-strip shall be when folded up. The signatures of the leaves (1 aresewed to the apexes of the folds of the stub-strip upon one side, whileto the apexes of the other side are attached the bridge-strips whichstrips are attached to the covers of the book in the usual manner. \Vhenthe book is opened the stiffening-strips 0 support the folds of the.

zigzag stub-strip and hold the end of the leaves up, so they willlieflat, while the flexible cloth, through which the sewing is easily done,forms a soft and flexible hinge for the leaves and for the bridge-stripsf. By placing a layer of cloth upon each side of the strips 0 the stripsare held securelyin place, cannot break out, and may be made quitethick, while the cloth, being double, may be made very thin andflexible.

I claim as my improvement- Abook the signatures of which are attached toa continuous stub-strip formed of two layers of thin flexible material,between which are held a short distance apart strips of much thickermaterial of nearly the width of the stubstrip when folded, the saidstub-strip being secured to the covers by bridge-strips, substantiallyas described.
